Methods were optimized for extraction and quantification of anthocyanins (ACY) and vitamin C in potatoes. Acidified aqueous methanol (70%) was the optimal extraction solvent and freeze-drying significantly improved the extraction yield of ACY. The content of ACY varied widely in five potato cultivars from 0.42 to 3.18mg/g dry weight, with the latter being the highest value found in the Finnish cultivar...

Okra is a widely accepted vegetable in subtropical and tropical regions due to the good palatability. However, the polysaccharide compositions remain unclear. In this work, the water extract of okra pod was prepared and the leading polysaccharide fraction was purified. The precise structural characteristics were identified. It was a polysaccharide ''rhamnogalacturonan'' as shown below, and the structure...

CdS photocorrosion seriously impeded its application in photocatalysis, especially for water splitting. Here we report new strategies to improve CdS photocorrosion resistance properties significantly by coating Ni2P shell and assembling an artificial gill to remove newly formed O2 from water. Ni2PΓdS catalyst can achieve the over-all water splitting under visible light irradiation without addition...

The topic of the paper is recognition of objects and patterns in color images regardless of their position, orientation, and scale. Gaussian-Hermite moment invariants designed especially for color images are introduced in this paper. We extend the existing invariants for graylevel images and show that in the case of color images there exist additional independent invariants, which can be constructed...

Accumulating evidence suggests that oxidative stress induced by beta-amyloid (Aβ) is implicated in the pathlogical progression of Alzheimer's disease (AD). 3H-1,2-dithiole-3-thione (D3T), the simplest compound of the sulfur-containing dithiolethiones, has been proved to be a strongly active antioxidant factor by regulation of the nuclear factor E2-related factor 2 (Nrf2). Previous study reported that...

Background
The overproduction of IgE plays a critical role in the pathogenesis of allergy; the mechanism is unclear. Histone‐acetyltransferase (HAT) activities are required in gene transcription of a large number of molecules in the immune system of the body.
Objectives
This study tests a hypothesis that HAT Tat‐interactive protein 60 (Tip60) plays an important role in the initiation of IgE‐mediated...

Cefquinome (CEF) is widely used for veterinary clinical applications because of its broad spectrum and high efficiency. However, frequent administrations are required due to its short elimination half‐life. In this study, cefquinome sulfate gelatin microspheres (CEF‐GMS) were prepared as a sustained‐release formulation using emulsion chemical cross‐linking technique. Physical properties, stability,...

The development of high efficient materials or devices for storage and utilization of sustainable thermal energy should be of great importance in alleviating energy crisis. Herein, we reported the fabrication of superwetting polypropylene (PP) aerogel as the support materials for construction of form-stable phase change materials (PCMs) composites. Due to its abundant porosity, light weight of aerogel...

The formations of stacking fault tetrahedra in {111}fcc/{111}fcc multilayers have been studied extensively, but the researches related to {001}fcc/{001}fcc interfaces can rarely be found in the literature. Using molecular dynamics (MD) simulations, the shock-induced dislocation structure in Ni/Al multilayers was studied in this article, the stacking fault pyramids (SFPs) initiated from Ni/Al interface...

Here, we present a dual amplification strategy based on a duplex-specific nuclease and a hybridization chain reaction, which has been designed for the highly sensitive detection of miRNAs. In the first step, a loop amplification strategy based on a duplex-specific nuclease was employed to obtain a large number of ssDNA reporters that then act as initiators to trigger the next amplification step. The...

This paper reports a novel method to prepare the antifouling composites with properties of self-adaptive controlled release (defined as control the release rate autonomously and adaptively according to the change of environmental conditions) by intercalation of sodium paeonolsilate (PAS) into MgAl and ZnAl layered double hydroxide (LDH) with the molar ratio (M2+/M3+) of 2:1 and 3:1, respectively....

Considering the negative effects on human health, the number of particles has been limited in the current standard emissions regulation. So an experimental study has been carried out to explore the behavior of the particles in a diesel/natural gas dual-fuel engine. In this paper the particle emissions characteristic of a diesel/natural gas dual-fuel engine with varying engine loads at constant engine...

In this article, a combined experimental and computational study was conducted to investigate the heat transfer characteristics of sonic impingement jets on the concave surface of the leading edge of a NACA0015 airfoil. Both the local/average Nusselt number (Nu/Nu ) distributions and flow pattern in the impingement region were obtained for H/d ranging from 10 to 25, S/d from 20 to 35, and d from...

This paper presents a nonlinear convergence algorithm for active dynamic undamped vibration absorber (ADUVA). The damping of absorber is ignored in this algorithm to strengthen the vibration suppressing effect and simplify the algorithm at the same time. The simulation and experimental results indicate that this nonlinear convergence ADUVA can help significantly suppress vibration caused by excitation...

The phase transition characteristics, dielectric relaxation behavior, and ferroelectric hysteresis in undoped and Mn-doped 0.24Pb(In1/2Nb1/2)O3-0.42Pb(Mg1/3Nb2/3)O3-0.34PbTiO3 (24PIN-42PMN-34PT) ternary ceramics have been investigated. The degree of diffuse phase transition (DPT) is enhanced by the addition of manganese due to the disorder-enhanced structure. The temperature dependence of the dielectric...

We investigate the formation mechanism of prismatic loops in a 3C-SiC single crystal subjected to nanoindentations on its (111) and (110) surface with a fictitious spherical indenter using molecular dynamics simulation. On the (111) surface, the simulated plastic deformation proceeds with the nucleation and expansion of shear loops, which react with each other to form prismatic loops eventually. Further...

We performed molecular dynamics (MD) simulations for the responses of single crystal (SC) and nanotwinned (nt) diamond films under nanoindentation, respectively, aimed to uncover the effects of twin boundary (TB) and twin thickness (δ) on hardness (H) and the corresponding deformation mechanisms. We found the Hall-Petch type relationship between H and δ. We also found that the inelastic deformation...

The inclusion complexation behaviors of glycyrrhetic acid (CTA) with four polyamine-modified β-cyclodextrins (CDs) have been investigated by 1H and 2D NMR, thermal gravimetric analysis, X-ray power diffraction and scanning electron microscopy. The results showed that Glycyrrhetic acid was encapsulated into the cavity of cyclodextrin to form the complexes with 1:1 stoichiometry. The water solubility...
